Bluehole expected PUBG to sell less than 300k in the first year

When Brendan 'PlayerUnknown' Greene pitched the Battlegrounds concept to Korean developer Bluehole, a lot of the in-house industry veterans didn't think it would sell more than 300,000 units in the first year, he told Polygon.

He had higher hopes, expecting around a million copies in the first month, but even that was surpassed as it sold over two million in around five weeks.

"A lot of the [internal team], they really couldn't believe it," he told Polygon. "There was a few veterans of the game industry that were [saying], like, 'No, no. 200,000 [or] 300,000 the first year.' But then when we hit that first million, there were a lot of smiles around the office."

From then on, as everyone knows, the Battlegrounds hype train just hasn't stopped. They recently hit the 10 million copies sold milestone, along with one million concurrent players, and it's simply continuing to grow.

"I mean, we're walking around wondering why we've been this successful," Greene said. "You know, I had faith in my own game mode ... but [10] million copies and number one on Steam in just under five months I think we're at now? It's just crazy to me."

We spoke to Greene at Gamescom, where he delved some interesting information about cross platform play and upcoming maps and modding tools. Check out the full interview below and let us know your thoughts in the comments.
